Everton – Amadou Onana (€30m)
The Toffees beat West Ham to the Belgian international’s signatures last summer.
It is fair to say that Onana has had his ups and downs during his first season in the Premier League.
While he has started 28 league games, his performances have been inconsistent, which isn’t completely surprising for a 21-year-old.
If the Merseysiders are relegated, plenty of rival Premier League teams are likely to pursue his signature.
